dynamically create date for previous sunday at 12:00 AM

Question

I\'m struggling to figure out how to dynamically create a date object for the most previous sunday at 12:00 AM

I was thinking I could get today\'s date and then subt

@AndreasLey solution in Swift 2.0:

  func getLastSunday() -> NSDate?
{
    let today = NSDate();
    let calendar : NSCalendar! = NSCalendar(calendarIdentifier: NSCalendarIdentifierGregorian)
    calendar.locale = NSLocale(localeIdentifier: "en-US") // force US locale, because other countries (e.g. the rest of the world) might use different weekday numbering

    let flags : NSCalendarUnit = [.Year , .Month, .Weekday, .WeekOfMonth, .Minute , .Second]
    let nowComponents = calendar.components(flags, fromDate: today)

    nowComponents.weekday = 1 //Sunday
    nowComponents.hour = 0  // 12:00 AM = midnight (12:00 PM would be 12)
    nowComponents.minute = 0
    nowComponents.second = 0;


    let  previousSunday = calendar.dateFromComponents(nowComponents);
    return previousSunday
}
